A practical, private image enlarger

This tool uses the browser’s best image resampling and an optional detail pass. It is ideal for screenshots, diagrams, product images, and modest photo enlargement. It does not invent detail or send pixels to a model.

Supported files

Open PNG, JPEG, WebP, GIF, AVIF, and other image formats your browser can decode. The enlarged result is exported as PNG.
